[The main postulate of the vertical evolution theory].

In the series of previous publications by the author (2000, 2002, 2005), a genetic model explaining the phenomenon of evolutionary progress was presented. In the present paper, this model is described in general terms. The model is based on views on regular changes of ecological potential of organisms on a macroevolutionary time scale. According to these views, macroevolution has its own pattern, which cannot be seen in the microevolutionary process. Hence, the statement of the synthetic theory of evolution that "macroevolution proceeds via microevolution" is incorrect.
